Sm. Handwerker et al., SERUM IONIZED MAGNESIUM LEVELS DURING INTRAVENOUS MGSO4 THERAPY OF PREECLAMPTIC WOMEN, Acta obstetricia et gynecologica Scandinavica, 74(7), 1995, pp. 517-519
Using a novel ion-selective electrode, we have shown that there is ove
r a 100% increase in venous serum levels of ionized Mg during intraven
ous MgSO4 therapy of preeclamptic patients. By 6 hours of therapy, the
range is 0.92-1.65 mmol/l (95% C.I.). There are strong correlations b
etween levels of ionized and total Mg throughout therapy (r=0.92-0.95,
p<0.01).
